U-Filter Installation and maintenance

Prerequisites

  • Operating System: Ubuntu 20.04 or above.
  • NTP server: An NTP server (global or internal) must be accessible, as it is crucial to know what time it is at all times in case of a live alarm system.

Example NTP Configuration

  1. Install NTP.
sudo apt-get install ntp
  1. Configure NTP Server.
sudo nano /etc/ntp.conf

In this configuration file, you can specify the NTP servers to which your machine will synchronize. These servers are specified in lines that begin with “server”. For example:

server 0.ubuntu.pool.ntp.org iburst
server 1.ubuntu.pool.ntp.org iburst
server 2.ubuntu.pool.ntp.org iburst
server 3.ubuntu.pool.ntp.org iburst
  1. Allow NTP through the firewall. If you have a firewall enabled, you need to allow NTP through it. NTP uses UDP port 123, so you will need to allow this port through the firewall.
